Alternative Fuels (Alt-Fuel)

Alternative fuels are non-traditional energy sources used to power vehicles instead of gasoline or diesel, often chosen for environmental, regulatory, or cost-related reasons.

Common types include:

• Electricity (EVs): Battery-powered vehicles with zero tailpipe emissions
• Compressed natural gas (CNG): A lower-emission fossil fuel alternative
• Propane (LPG): A clean-burning fuel commonly used in fleet vehicles
• Hydrogen: Used in fuel cell vehicles, producing only water vapor as a byproduct
• Ethanol blends (e.g., E-85): Renewable fuel made from plant-based materials

Alternative fuels are often used to reduce greenhouse gas emissions, meet sustainability goals, and comply with environmental regulations. In some cases, they can also offer lower operating costs, depending on fuel prices and usage patterns.

However, adoption depends on practical considerations like fueling or charging infrastructure, upfront vehicle costs, range requirements, and how well the vehicle fits day-to-day operations. In practice, not every alternative fuel vehicle is a fit for every role, especially in distributed or high-mileage driving environments.
